There was a guy on SRP years ago named Bart, from Belgium. A coticule connoisseur, and said to be quite a honer.

He was the first person I ever heard to suggest dulling the edge on a water glass. In that case it was so the honer was starting from zero and wasn't getting 'false positives' in his sharpness tests as he progressed in the honing.

Not to contradict Glen, he has undoubtedly honed way more razors than I have, but, having tried it once after Bart posted the suggestion, I've never 'killed' an edge since and so far so good. Interesting that it worked so well for you.

If I ever run into that situation maybe I'll give it another try.
